Description
British-Grown Wild Bird Food
If you love watching robins, blackbirds and other garden visitors feed, Dried Calci Worms give them something worth coming back for. They’re 100% dried Black Soldier Fly larvae (Hermetia illucens) — British-grown, gently drum dried, and packed with naturally occurring calcium, with nothing else added.
Why Choose Dried Calci Worms?
- Grown in Britain — British-grown larvae with clear UK provenance, fed on UK vegetable by-products.
- Gently drum dried — dried in Britain rather than microwaved, keeping them as close to natural as possible.
- 100% natural — 100% Black Soldier Fly larvae, no additives, nothing else in the pouch.
- Up to 50x more calcium than dried mealworms — a genuinely higher-calcium option for the birds in your garden.
Grown in Britain
From growing to packing, Dried Calci Worms follow a short, clearly traceable UK supply chain: grown in Britain, fed on UK vegetable by-products, drum dried in Britain, then packed by us here at Syntects in Staffordshire, England.
Why Are They Darker?
You may notice our Calci Worms look a shade darker than some other dried larvae on the market. That’s simply the result of gentle drum drying rather than another method — it’s not a sign of anything being wrong, just part of what makes them distinctive.
